Motions of tissues within patient body are an indispensable part of body functions. They may have character of relatively periodic and predictable patterns (like motions due to respiration, heart beat, blood transport) or result from peristalsis and other spontaneous movements of organs or liquids and gasses residing in the anatomy. If not properly accounted for these motions can degrade the quality of diagnosis and medical interventions. This workshop focuses therefore on methods to observe, model, predict and actively compensate, or even utilize for treatment advantage, such motions in patient body to prevent the decrease in treatment quality and efficiency. Ideally, all submissions should highlight the clinical application and the need for real-time motion compensation. We are soliciting submissions of papers presenting novel results.
